  After your heart has stopped beating and you are no longer breathing, your brain will keep on working for a while – maybe about 7-10 minutes. Im not really sure what is going on in your brain during this time…perhaps this is when your life flashes before or eyes, or you have a dream like experience – I suppose this is why some people who have had “near death experiences” sometimes say that they saw a light, or that they had some sort of experience when their heart had stopped.

  Yeah what is currently thought is just what Nicola has said. I doubt it’s any conscious thought activity though – that would be a bit rubbish, I dont want to die and be thinking about it.
